IMPROVEMENT IN ROOFING.

Specification forming part of Letters Patent No. 22 l,0S0,'d t 1 October 2 1 7 IPP M7 11 filed July 26, 1879.

To all whom it may concern:

Be it known that I, BERNHARDT LOHSE, of Niederau, near Meissen, Germany, have invented a new and useful Improvement in Roofing, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure 1 is a longitudinal vertical section in line 00 m, Fig. 2. Fig. 2 is a top or plan view of a portion of a root embodying my invention. Fig. 3 is a side view thereof. Fig. 4 is a perspective view thereof.

Similar letters of reference indicate corresponding parts in the several figures.

My invention consists of roofing-boards and fillets connected by ton gue-and-groove joints, and provided with a cap or covering, so as to prevent separation of the boards and roof and tightly close the joints between the same.

Referring to the drawings, 6 represents boards which are properly laid to form a roof, and b the fillets placed over the joints of adjacent boards, and secured thereto.

On the under side of the fillets are tongues 01, and on the upper sides of the boards, adjacent to the sides thereof, are grooves d, which receive said tongues.

A covering, 0, of sheet metal is secured to the fillets b, and thus the joints of the fillets and of the boards are protected thereby.

injected into the pores of the wood, using,

preferably, chloride of zinc,whereby the boards are protected from rot and combustion.

My roof will be found to be light, cheap, and serviceable.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

The boards 6 and fillets b, with tongue-andgroove connections at d, in combination with a cap or covering, substantially as and for the purpose set forth.

BERNHARDT LOHSE.
